DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 465,759, dated December22, 1891.

Serial No. 388,245. (No model.)

To all whom it may 0072106777.:

Be itknown thatLPAULEMERsoN GLAnoKE, of Cheyenne, in the county ofLaramie and State of \Vyoming, have invented a new and ImprovedDumping-Oar, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a 'new and improveddumping-car, which is simple and durable in construction, arranged todump automatically when the door is unlocked, and adapted to dischargethe load in any desired direction.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement, with parts in section.Fig. 2 is a plan View of the same with parts broken out. Fig. 3 is arear end view of the same, and Fig. 4 is a plan view of the plate onwhich the frame turns.

, The improved dumping-car is provided with a wheeled truck A, on thetop of which is secured a circular plate 13, in which lies afriction-plate B, over and upon which rests a correspondingly-shapedturn-table 0, supporting a frame D, mounted to turn on a pivot E, heldin the circular plate B. The frame D supports a receptacle F, providedwith an inclined bottom F; sides F extending upwardly and outwardly fromthe said bottom, and an end F arranged at the upper end of the bottom Fand connected with the sides F The other end of the receptacle F isopen, and is adapted to be closed by a door G, hinged at its upper endon a rod II, extending transversely and supported on the sides F of thereceptacle F.

Near the lower end of the door G and at one side thereof is secured apin I, which extends beyond the side of the receptacle and is adapted toengage a notch J in a latch J pivoted at- J to the respective side F ofthe receptacle F. The latch J is in the shape of a lever, and has itsrear end pivotally connected with a rod K, extending longitudinally tothe rear end of the frame D and formed on its rear end with a handle KThe rod K passes through an opening formed in a lug D secured on astandard D, supporting the rear end of the receptacle F. hen the latch Jis in the position shown in Fig. 1, the end having the notch J extendsupward, so as to-be readily engaged by the pin I when the door G isclosed. WVhen the operator pulls on the handle K, the notched end of thecatch swings downward, so as to disengage the pin I to unlock the doorG.

In order to hold the door in an open position, as plainly illustrated inFig. 1, a rod L is provided, which extends longitudinally and ispivotally connected with one side of the door, the rear end of the rodbeing formed with a handle L and with a series of teeth L adapted toengage a loop L secured to one side F of the receptacle F. The saidteeth L are arranged as shown in Fig. 1, so that when the door G swingsopen one of the teeth engages the loop L so that the said rod L islocked in position and the closing of the door G is prevented.

\Vhen the operator desires to close the door, he takes hold of thehandle L and pulls upward, so as to disengage the respective tooth Lfrom the loop L whereby the door G is unlocked, and the door closesautomatically, owing to its tendency to assume a vertical position.

In order to lock the frame D, carrying the receptacle F, to the wheeledtruck A, a locking-arm N is provided, which extends vertically and ispivoted at its upper end at l to the frarneD, the free end of the saidarm N being adapted to pass into a notch C in the turn-table O and oneof a series of notches B formed in the periphery of the plate B. Thefree end of the arm N is also pivotally connected with a rod 0,extending rearwardly and passing through a transverse brace D held onthe standard I). The outer end of the rod 0 is formed with a handle 0',and near the latter and on the under side of the rod is formed a notch 0adapted to engage the brace D so as to hold the rod 0 in a lockedposition at the time that the arm N is disconnected from the notch B inthe plate B1 The operation is as follows: Vi hen the receptacleF is tobe loaded, the door G is closed, its pin I being engaged by the catch.I.

The

truck A can then be moved to the place on which the load is to bedumped, and then the operator pulls on the rod 0 until the notch 0 dropsinto the brace D This movement of the rod 0 disengages the arm N fromthe respective notch B in the plate B so that the frame D, carrying thereceptacle F, can now be turned to any desired direction to bring thefront end of the receptacle F to the point of dumping. IVhen thisposition is reached, the notch O is disengaged from the brace D so thatthe arm N swings to its normal position and engages the correspondingnotch B in the plate 13. The frame D isnow locked in position, and theload is now dumped automatically by the operator pulling on the rod K,so as to disengage the notch J of the catch J from the pin I. Thepressure of the load in the receptacle F on the door G now causes thelatter to swing outward, so that the load slides down the inclinedbottom F of the receptacle F to the ground at the proper place. Vv henthe load pushes the door G open, the rod L is drawn forward, so that oneof its teeth L finally engages the loop L to lock the door G in an openposition, as shown in Fig. 1. The load readily discharges automaticallyfrom the receptacle F as soon as the door G is opened, on account of theinclined bottom F and the flarin g sides F hen the load is discharged,the operator disengages the tooth L from the loop L so that the door.Gswings into a vertical position and again engages with its pin I thenotch J of the catch J. The operator then pulls the rod 0, so as todisconnect the pivoted arm N from the respective notch B to enable theoperator to turn the frame D back to its normal position. (Illustratedin Fig.1.) Thus it will be seen that the dumpin g-carautomaticallydischarges its load whenever the door is unlocked and the receptacle Fcan be brought in such a position as to discharge its load at the properplace, either at the side or ends of the wheeled truck.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The car-body F, formed with an inclinedbottom widest at its lower end, a narrow upper closed end F, the sides Fdiverging at their lower ends, the door G, pivoted at its upper edge inthe loweropen end of said body, and means for locking the door,substantially as set forth.
